The graphical solution to a systems of equations is the coordinate pair at the place where the two linear graphs intersect.

What is the graphical solution to a systems of equations

The graphical solution to a system of equations is a method of finding the point of intersection between the graphs of the equations. We plot each equation as a line on the same coordinate plane, and then find the point where the lines intersect.

If we have two equations in two variables, the solution to the system is the point where the two lines intersect. Also if there are three equations in three variables, the solution is the point where the three planes intersect.

In conclusion, the graphical solution to a systems of equations is the coordinate pair at the place where the two linear graphs intersect.

having a low probability, unique

Answers

Originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.

Originality refers to the quality of being unique, new, and innovative. It involves creating something that has not been seen or experienced before. The best description of originality is that it is having a low probability and being unique.

An original idea, product, or work of art is something that has not been copied or imitated from others. It represents a new perspective or approach that can offer a fresh insight into a problem or challenge. Originality requires a high level of creativity, imagination, and inspiration, as well as a willingness to take risks and explore new possibilities.

Nonobviousness is also an important factor in originality. It means that the idea or invention is not something that would be obvious to someone skilled in the same field or industry. In other words, an original idea should not be something that could be easily predicted or anticipated.

Special or interesting are also characteristics of originality, but they are not sufficient to define it. An idea or product can be special or interesting without being truly original. For example, a new flavor of ice cream may be interesting, but it may not be original if it has already been created by someone else.

Convergent thinking, on the other hand, involves finding a single solution to a problem. It is the opposite of divergent thinking, which involves generating multiple ideas and possibilities. Convergent thinking is important for finding effective solutions to problems, but it is not the same as originality.

In conclusion, originality is the quality of being unique, new, and innovative. It requires creativity, imagination, inspiration, and nonobviousness. Special or interesting aspects may be present, but they are not sufficient to define originality.

Which of the following new vehicle borrowers is likely to be offered the lowest APR?

A. Tyler who is buying a used vehicle and has a FICO score of 780

B. Daniel who is buying a used vehicle and has a FICO score of 600

C. Stephanie who is buying a new vehicle and has a FICO score of 780

D. Emily who is buying a new vehicle and has a FICO score of 600

Answers

Answer: C. Stephanie who is buying a new vehicle and has a FICO score of 780.

Step-by-step explanation: The Annual Percentage Rate (APR) is the interest rate charged on a loan.  Lenders consider various factors when determining the APR, including the borrower's credit score and the type of vehicle being financed.

In this scenario, Stephanie has a FICO score of 780, which indicates a strong credit history and responsible financial behavior.  Lenders generally view higher credit scores as an indication of lower credit risk.  As Stephanie is buying a new vehicle, lenders may consider this a lower-risk loan compared to financing a used vehicle.

Lower credit risk and the lower risk associated with financing a new vehicle are factors that could result in Stephanie being offered a lower APR compared to Tyler (option A), who is buying a used vehicle, and Daniel (option B), who has a lower FICO score of 600.

It's important to note that other factors, such as the lender's policies, market conditions, and individual loan terms, can also influence the APR offered to borrowers.

The volumes of two similar figures are given. The surface area of the larger figure is given. Find the surface area of the smaller figure.
V= 160 meters cubed
V= 2500 meters cubed
S.A. = 1400 meters squared

Answers

Answer:

Since the figures are similar, their corresponding side lengths are proportional.

Let x be the scale factor between the larger and smaller figures. Then, the volume of the larger figure is x^3 times the volume of the smaller figure.

We can set up an equation to solve for x:

2500 = x^3 * 160

Divide both sides by 160:

x^3 = 2500/160

x^3 = 15.625

Take the cube root of both sides:

x = 2.5

So, the scale factor between the larger and smaller figures is 2.5.

Since surface area is proportional to the square of the scale factor, we can set up another equation to solve for the surface area of the smaller figure:

S.A. of smaller figure / S.A. of larger figure = (scale factor of smaller figure)^2 / (scale factor of larger figure)^2

Solving for the surface area of the smaller figure:

S.A. of smaller figure / 1400 = 2.5^2 / 1^2

S.A. of smaller figure / 1400 = 6.25

S.A. of smaller figure = 6.25 * 1400

S.A. of smaller figure = 8750

Therefore, the surface area of the smaller figure is 8750 meters squared.

A truck Can be rented from company A for $60 a day plus $0.30 per mile. Company B charges $40 a day plus $0.70 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost for company A a better deal than company B’s?

Answers



Let's represent the number of miles driven in a day by "m".

The cost of renting from company A can be represented by the equation:
Cost_A = 60 + 0.3m

The cost of renting from company B can be represented by the equation:
Cost_B = 40 + 0.7m

To find out how many miles must be driven in a day to make the rental cost for company A a better deal than company B's, we need to set the two equations equal to each other and solve for "m":

60 + 0.3m = 40 + 0.7m

Simplifying the equation, we get:

20 = 0.4m

Dividing both sides by 0.4, we get:

m = 50

Therefore, if the number of miles driven in a day is greater than 50, it would be more cost-effective to rent from company A. If the number of miles driven is less than 50, it would be more cost-effective to rent from company B.

Two boards are placed end to end to make a walkway. One board is 6 feet 11 inches long, and the other board is 5 feet 7 inches long. How long is the walkway?
Write your answer in feet and inches. Use a number less than 12 for inches.

Answers

The walkway is 11 feet 6 inches long.

To find the length of the walkway, we need to add the lengths of the two boards.

The first board is 6 feet 11 inches long, which can be written as 6 + 11/12 feet using the fact that there are 12 inches in a foot.

The second board is 5 feet 7 inches long, which can be written as 5 + 7/12 feet.

Now we can add the lengths of the two boards:

6 + 11/12 feet + 5 + 7/12 feet

= 11 + 6/12 feet

=11 + 1/2 feet

Therefore, the walkway is 11 feet 6 inches long.

Lauren kicks a football. Its height in feet is given by h - _ 16t2 + 56t where t represents the time in seconds after kick. Interpret the coordinates of the vertex in context.

Answers

Answer: 49.2 feet

Step-by-step explanation:

The given equation h = -16t^2 + 56t represents the height of a football kicked by Lauren as a function of time t in seconds.

In the context of the problem, the vertex of the parabolic function (-16t^2 + 56t) represents the point at which the football reaches its maximum height. The vertex of a parabola is the point where the function reaches its highest or lowest value, and it is given by the coordinates (h, t) in this case.

Interpreting the coordinates of the vertex in context, the h-coordinate represents the maximum height of the football, while the t-coordinate represents the time at which the football reaches that maximum height. So, if we determine the vertex of the given function, we can interpret the maximum height and the time it occurs.

The formula for the x-coordinate (t) of the vertex of a quadratic function in the form y = ax^2 + bx + c is given by t = -b/2a. Comparing this with the given equation, we can identify that a = -16 and b = 56.

Plugging in the values of a and b into the formula, we get:

t = -56 / (2 * -16)

t = -56 / -32

t = 1.75

So, the t-coordinate of the vertex is 1.75 seconds, which represents the time at which the football reaches its maximum height.

To find the h-coordinate of the vertex, we can substitute the value of t we found (1.75) into the given equation:

h = -16(1.75)^2 + 56(1.75)

h = -16(3.0625) + 98

h = -48.8 + 98

h = 49.2

So, the h-coordinate of the vertex is 49.2, which represents the maximum height of the football in feet.

In conclusion, the coordinates of the vertex (49.2, 1.75) in the given context represent the maximum height (49.2 feet) of the football and the time (1.75 seconds) at which the football reaches its maximum height after being kicked by Lauren.

Eli has 38 in cash and 72 on gift card he says that when he rounds to the nearest 10 tickets he has about a $100 is he correct explain

Answers

Eli's statement is incorrect. Since $10 is greater than $5, we cannot round $110 to $100 when rounding to the nearest 10.  

   

To determine if Eli is correct, we need to add the amount of cash he has with the value of his gift card;      

$38 + $72 = $110

Since Eli says that he has about a $100 when he rounds to the nearest 10, we need to check whether $110 rounds to $100 or not. To round to the nearest 10, we look at the last digit of the number, which is 0 in this case. If the last digit is 5 or greater, we round up to the next multiple of 10. If the last digit is less than 5, we round down to the previous multiple of 10.

Since the last digit of $110 is 0, we don't need to round up or down. $110 is already a multiple of 10. Therefore, Eli is incorrect in saying that he has about a $100 when he rounds to the nearest 10. He actually has $110.  

Alternatively, we can check if $110 is within $5 of $100, which is the threshold for rounding to the nearest 10.

$110 - $100 = $10

Therefore, Eli's statement is incorrect.

We can use the standard form of the quadratic function, which is f(x) = ax^2 + bx + c, to write an equation for this function.

First, we can find the value of "a" by using the fact that the function is quadratic. We know that the second differences between the values of f(x) are constant, which means that a = 1/2(16 - 2(15) + 12) = -1/2.

Next, we can use the point (0, 15) to find the value of "c". Plugging in x = 0 and f(x) = 15, we get:

15 = (-1/2)(0)^2 + b(0) + c

So c = 15.

Finally, we can use another point, such as (-4, 12), to find the value of "b". Plugging in x = -4 and f(x) = 12, we get:

12 = (-1/2)(-4)^2 + b(-4) + 15

Simplifying this equation, we get:

12 = 8 - 4b + 15

-11 = -4b

b = 11/4

Putting it all together, we get the equation:

f(x) = -1/2x^2 + 11/4x + 15

determine the exact values of x for x^2 - 8x - 5 = 0

Answers

The exact values of x for x² - 8x - 5 = 0 are x = 4 + √21 or x = 4 - √21

To solve for x in the equation x² - 8x - 5 = 0, we can use the quadratic formula, which is:

x = (-b ± √(b² - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.

Using this formula, we can identify the values of a, b, and c in the equation x² - 8x - 5 = 0.

Here, a = 1, b = -8, and c = -5.

Substituting these values into the formula, we get:

x = (-(-8) ± √((-8)² - 4(1)(-5))) / 2(1)

Simplifying this expression, we get:

x = (8 ± √(64 + 20)) / 2

x = (8 ± √84) / 2

Now, we can simplify the square root of 84 as 2√21:

x = (8 ± 2√21) / 2

We can further simplify this expression by factoring out 2 from the numerator:

x = 2(4 ± √21) / 2

Answers

The monthly income of the first person is $600.

Given that, the average monthly income of three persons is RS 3,600.

The income of the first is 1/5 of the combined income of the other two.

Here, Let income of the first be A, let income of the second be B and let Income of the third be C.

A+B+C=3600 -----(i)

Income for the first person = 1/5(B+C) -----(ii)

Substitute equation (ii) in equation (i), we get

(B+C)/5 +B+C =3600

B+C+5B+5C=3600×5

6B+6C=18000

6(B+C)=18000

B+C=3000 ------(iii)

Substitute (iii) in equation (i), we get

A=$600

Therefore, the monthly income of the first person is $600.

Developing an estimated regression equation for these data

From the question, we have the following parameters that can be used in our computation:

Observation 1 2 3 4 5 6 7 8 9

xi 2 3 4 5 7 7 7 8 9

yi 4 5 4 6 4 6 9 6 11

Using a graphing tool, we have the following calculation summary

Sum of X = 52Sum of Y = 55Mean X = 5.7778Mean Y = 6.1111Sum of squares (SSX) = 45.5556Sum of products (SP) = 31.2222

Regression Equation: ŷ = bX + a

Where

b = SP/SSX = 31.22/45.56 = 0.68537

a = MY - bMX = 6.11 - (0.69*5.78) = 2.15122

So, we have

ŷ = 0.68537x + 2.15122

Rounding the numerical values to two decimal places, we have

ŷ = 0.69x + 2.15

Hence, the estimated regression equation for these data is ŷ = 0.69x + 2.15
